  • Continuous variables are presented as a/b/c where a=25th percentile, b=median, and c=75th percentile. Categorical variables are presented as percent (number). Note that there were no nonmissing values, except for percentile ranking, for which there were data for 389 R01 grants and 160 R01 (ARRA) grants. Continuous variables were compared with the Wilcoxon test and categorical variables with the Pearson test. ARRA indicates American Recovery and Reinvestment Act; and SEP, special emphasis panel.
